In our quality control laboratory we do control permanently the following parameters:

 

Mechanical properties:

- Tensile strength (S2) (according to DIN 53504) - Elongation at break (according to DIN 53504) - Modulus 300% (according to DIN 53504) - Hardness (according to DIN 53504) - Tear strength (according to DIN ISO 34-1)

 

 

Rheological properties:

- Mooney viscosity (ML1+4; 100°C) (according to DIN 53523) - Rheometer Monsanto 2000 E (according to DIN 53529) - Minimum torque - T10 - T90 - Maximum torque

 

 

On special demands we or our German main company can perform some other examinations like:
